' Application filed May 20. 1913. Serial No. 768,75fl.

ten pin of conventional form is illustrated i which is constructed of composite layers A of material fitted andcemented upon a central doWel.

The ob'ect of the invention is lo )reduce wardly and into the center' dowel 3.

articles of this character of strong and durable construction and extremely long life `and which will not split or chip olf when in operation. I

ln the accompanying drawings-Figure 1 is a side elevation of the improved pin. Fig.- 2 is a central longitudinal section through the improved pin. Fig. El is a view of the hard liber shock sustaining disk detached from the remainder of the pin. Fig. 4 is a detached view of the metal center piu for the dowel.

ln referring to the preferred adaptation of the invention shown in the accompanying drawing's in detail` like numerals designate like parts.

The bowling or ten pin shown is con structed or superimposed alternate relatively thin sheets or layers of Wood such veneer l and paper or other suitable fabric such as straw board Q which are fastened firmly to each other .with cement, a central dowel 3 which passes longitudinally throughthe superimposed sheets or layers, an end reinforcement 4 of hard liber, and a disk 5 of hard liber which is inserted in an intermediate portion of the pin in position to be struck by the ball and is adapted to receive and sustain the striking shock of the. ball. i

ln order to positively fasten the end reinforcement in place', the lower end of the central dowel which is preferably made of Wood is enlarged and ,taperedl as shown at 6, in Fig. 2, and a Central beveled opening is cut in the. reinforcement 4: in which the tapered portion 6 dovetals and locks.

.i reinforcement 7 of hard ber similar to the end reinforcement may be fitted on the top of the pin as shown in l and Q.

The wooden dowel 3 is made compara tively larger in diameter, of rectangular or oval shape to hold the composite board securely when turning and extending 'lon gitiulinally throughout the pin from the top to the bottoni thereof. and said dowel is reinforced throughout the greater portion of its length or from the top of the pin to a point below the striking1 point of the ball by a metal core or pin S which is driven snugly and rigidly in a central longitudinal opening in the wooden dowel. as shown in Fig.

l`o secure the lop reinforcement T in place, one or more lsmall supplementary dowels fl are driven through the reinforcement T in a diagonal direction or downwardly and in- These improved articles are ivireferablyconstructed as follows: Alternate' sheets of veneer and straw board are superimposed upon and cemented to each other to the thickness of about one-half an inch, thc coniposite or builtup board is then put in a sui table press for twelve to twenty-four hours and at the expiration of the time it is rcmoved from thc press and placed in a drying room having anapproximate temperature of about eighty degrees. ln making a pin, the composite or built up boards, which have been cut or stamped to a size slightly larger than the diameter of the pin at its different points, with a central open ing to snugly fit the dowel rlhe hard fiber reinforcement't is first slipped or fitted on the lower end ofthe dowel 3 and dovetailed locked thereon as before described. Sullicient composite boards are fitted on the dowcl 3 over the reinforcement el to build the pin up to the point just below where the pin is struck by the ball, and the liber disk 5 is then fitted on the doivel over the boards. The composite boards necessary to build the pin up to the desired length are then placed on the dowcl over the fiber disk. The partially completed pin is now put in a press for a certain number of hours or over night, after which it is placed in a drying roomf'or about forty-eight hours and is then finally finished by turning it to the desired size in a suitable lathe and coating it with varnish or other suitable material.

It should be understood that the construction of this improved article may be altered,

or changed or some of the parts thereof mayV posed sheets and a metal reinforcing pin centrally tted in said doWel.

2. An` article of the class described composed of a series of 4relatively thin sheets of material -superimposed upon and cemented to each other and cut to conform tothe desired shape and an intermediate disk of hard fiber interposed between the sheets in position to receive the blows and sustain the shock of'an impinging article.

3. An article of the class described composed of a series of relatively thin sheets of material superimposed upon and cemented to'each other and cut to conform to the desired shape,l a central doWel extending lon- 'itudinally through the superimposed sheets of material, top andbottom end reinforcelments of hard liber, and an intermediate shock sustaining disk of hard fiber.

4. An article of the class described composed of a series of relatively thin sheets of material superimposed upon and cemented to each other and cut to conform to the desii-ed shape, a central doWel extending longitudinally through the superimposed sheets of material and having an enlarged ta ering end and an end reinforcement of har fiber dovetail locked in place on the tapering end of the doWel.

5. An varticle of the class described composed of a series of relatively thin sheets of material superimposed upon and cemented to each other and cut to conform to the desired shape, a central doWel extending longitudinally through the superimposed sheets of material, an end reinforcement, and

a small supplementary doWel extending diagonally through the end reinforcement Aand into the central doWel.

6. An article of the class described composed of a series of superimposed sheets of material such as veneer and paper in alternate arrangement pressed and cemented'toA gether and cut to conform to the desired shape, a central doWelV extending through the superimposed sheets of material, top and bottoni end reinforcements fitted on the top and bottom ends of the article, and an intermediate shock sustaining disk of hard ber. y l
